GAME cancelled my pre-order and I can't get Myth Heroes pack

I pre-ordered the game on March 4th and for some reason it got cancelled two-three days before and I was therefore unable to get the Myth Heros pack. GAME have been unhelpful.

They can't specify a reason why it's been cancelled. I had to re-preorder the game and it got delivered with no code. I'm trying to find out some answers and I'm hopinh SSM can send me one if GAME being the **bleep** they are can't help me.
